Hello TE5LA and others. I've been a long time lurker, but have always felt I really have very little to contribute against the astonishing expertise already expressed in this forum.
But now I can make a small contribution which may be of use to TE5LA. I invest in TSLA through an ISA (A kind of tax free sand pit for UK investors to play in). I use HSBC who provide an Invest Direct Account. Transaction fees are a little steep for US securities, about $30 per trade, but there is the benefit of not having to wait 3 days before redeploying the proceeds of a share sale. Sort of like trading on margin without having margin. It's a simple product...no fancy stuff like option trading or borrowing shares to short.
But I wouldn't want to short anyway...the mis-steps we have seen so far in TeslaMotors are in my opinion absolutely minuscule in comparison to the massive potential of the vision.
And by the way, I live in Cornwall also!
Ukland Wombat - Thanks very much for the advice, i'll check them out. It seems that most products are set up for the UK markets...
